JOSEPH'F. BUZBY, OF ROYERS FORD, PENNSYLVANIA INSULATOR.

SPECIFICATION forming part Of Letters Patent NO. 427,296, dated May 6, 1890.

7 Application filed December 31, 1889. Serial No. 336,497. (No model.)

To all whom it may concern:

1 Be it known that I, JOSEPH F. BUZBY, a citizen of the United States, residing at Royers Ford, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful-Improvements in Glass or other Insulators for Use with theWi res on Telephone or Telegraph Poles; and-I do declare the following to be a full, clear, and" exact descrip tion of the invention, su ch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

j The invention relates to insulators for use with the wires on telegraph or telephone poles {and it consists in the im proveni ent hereinafter described, and pointed out in the claim.

7 Figure 1 of the drawings is a side elevation showing my insulator with i ve wire therein V Fig. "2, a'ldetail perspective view of the insu ortelegraph-wire secured by an end hook a lator, and Fig; 3 a similar ,view Of'fih insulater-stand. I

In the drawings, A represents a telephone in the staple B of a standard .0. The latter has a square tenon c.'which fits a correspondih'g hole in the base-boardD.

represents my insulator, which has the central tapering vertical holee in its lower end to fit over an upwardly-tapering projection f on the insulator-stand F and a flange e,- which bears on a. corresponding flange f.

of the stand, the two. flanges being clampedtogether by a spring-latch G, made fast on the 1 side of the stand.

The insulator 'is provided-with the perpendicnlar slot e, in which the wire .rests, and an oblique angle to slot e so that oneend of slot e opens into the upper end of slot e while the other end of slot e opens into the lower end of slote In order to put the insulator on the wire, it is turned out of a perpendicular until the slot e is in the same plane with the wire, which is then readily entered. The insulator is then turned back to a perpendicular and so locked to its stand. The head 9 of the spring-catch projects over the flange f" of the stand, and, being inclined at g, yields to the insulator, flange e as the latter is pressed down, and then overlaps it, so as to hold the insulator E securely to its stand F. In the position shown in Fig. 1 of the. drawings the wire A lies across the vslot e and therefore cannot possibly escape.

The shank f of the insulator-stand is made to fit a hole in the base-board, to pass therethrough, and to have its flange f supported on the base-board.

Having thus described all that is necessary to a full understanding of my invention, what Iclaim as new, and desire to protect by Letters Patent, is-

An insulator having the hole e in its lower end and the flange e,--iu combination with a and spring-catch G, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH F. BUZBY'.
